One of the most common concerns expressed by residents to the Public Works Department is vehicles "speeding" through their neighborhood streets regardless of the posted speed limit signs.
One of the physical devices to control speeding is a "speed hump" which usually has positive results in slowing down motorists in the vicinity of the hump. A "speed hump" is a raised, rounded, arched section of asphalt pavement, 3" - 4" higher than the remainder of the road surface, and 12 feet wide that extends across the full width of the roadway surface whose primary purpose is to physically reduce the speed of vehicles traveling on the roadway.
Disadvantages of Speed Humps
Although residents of Titusville have the option of having a speed hump constructed on their street; there are disadvantages associated with speed humps as follows:
- Speed humps may cause delays for police, fire, and medical emergency vehicles
- Speeds may increase between humps as drivers speed to make up for lost time
- Speeds may increase over time as drivers get used to the feel of the speed humps
- Speed humps may increase noise levels as vehicles drive over the humps
- Traffic volume may be diverted on to adjacent streets as drivers seek alternate routes to avoid the speed humps
- Some motorists drive with their right wheels in the gutter or bike lane (if one exists) in order to minimize the impact of the humps
- Speed humps may have a negative impact on air quality and energy consumption due to the increased slowing and braking
- Motorcycles, bicycles, and low clearance vehicles must use extra care
Criteria to Install Speed Humps
Residents who desire a speed hump are not automatically eligible for one. Their street must meet certain objective criteria. Basically, the criteria are as follows:
- The street must be a local street only. Speed humps are not allowed on minor and major collectors or arterials such as Country Club Drive, Barna Avenue, Knox McRae Drive, etc.
- The street must be a minimum of 1,000 feet long
- The road must have no more than two lanes of traffic
- The 85th percentile speed must be at least 35 miles per hour (mph) with a minimum two way traffic volume of 1,000 vehicles per day, or if the 85th percentile speed exceeds 38 mph, the two way traffic volume is 70% of the required 1,000 vehicles per day (700 vehicles). (The 85th percentile speed is the speed at or below which 85% of the observed free flow vehicles are traveling.)
A valid petition must be received from a majority of residents (not necessarily property owners) who reside in homes abutting the street (such as corner lots or lots that extend from one block to another) or on the street segment that the speed hump is requested.
Residents may request petitions from the Department of Public Works by calling 321-567-3846. They will be sent free of charge. Documents sent include:
- 2 "Petitions for the Installation of Speed Humps"
- "the Amendments to the City of Titusville Policy on Speed Humps" dated July 21, 1997
- The "Speed Hump Warrants, Policies, and Procedures" (3 pages)
- "Other Considerations"
- "Signing and Markings" page and detail sheet
- "Additional Installation Details" sheet
- "Table I Speed Hump Warrants" sheet
Once a valid petition is received and the street is verified by the Engineering Division to be at least 1,000 feet long, the Street Maintenance Department will install traffic counters to record the two way 24 hour speed and traffic volume.
Final Disposition & Installation
If the warrant criteria are met, the City will install a speed hump at no cost to the residents. If the warrant criteria are not met, the petitioning residents may appeal to the Titusville City Council providing that they agree to pay in advance one half of the cost (or $750) for the installation. The City will pay the additional $750, construct the speed hump, and install the appropriate pavement markings and signage in a reasonable period of time.
